Bug #67516 [Opn->Fbk]: wrong mimetypes with finfo_file(filename, FILEINFO_MIME_TYPE)

Edit report at https://bugs.php.net/bug.php?id=67516&edit=1 ID: 67516 Updated by: cmb@php.net Reported by: spam2 at rhsoft dot net Summary: wrong mimetypes with finfo_file(filename, FILEINFO_MIME_TYPE) -Status: Open +Status: Feedback Type: Bug Package: Filesystem function related Operating System: Linux PHP Version: 7.0.11 -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: I can confirm that even latest master reports "application/octet-sream" for "php-mimtype-bug.gif" with the bundled magic. > well, in a perfect world on would be able to update > 'data_file.c' with the script in the source tree before compile > PHP, in the real world the file is updates, php builds but it > don't work I can't reproduce this (generating a new data_file.c from Debian Jessie's magic.mgc, compiling and using finfo works fine for me). Anyhow, please open another ticket with regard to this issue. However, it shouldn't be necessary to compile with a custom magic.mgc, because you could pass a custom magic.mgc directly as second parameter to finfo_open(). Would that work for you, i.e. would that produce the expected "image/gif"?

If you're interested in what the differences are, have a look at https://github.com/php/php-src/blob/master/ext/fileinfo/libmagic.patch. ------------------------------------------------------------------------ [2015-07-13 11:25:42] spam2 at rhsoft dot net as said i build PHP from the unpatched upstream sources, so the libmagic is bundeled and that exists from 5.5.13 until 5.6.11 while the file-package from Fedora (cli command file) recognizes it correctly, hence i even wrote admin scripts calling the file-cli from PHP the problem is that at least for Fedora the distributions file-package becomes often updates in case of bugs and wrong recognized samples and PHP is always behind :-( ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
